USERS’ REQUIREMENTS
THE MOVIE DATABASE
“I’m the owner of a small movie rental store. We have over 3,000 movies that we need to keep
track of. Each of our movies has a DVD or VHS tape number. For each movie, we need to know
its title and category (e.g., comedy, suspense, drama, action, war, or sci-fi).
Yes, we do have multiple copies of many of our movies. We give each movie a specific ID, and
then track which DVD or VHS contains the movie. A movie can be either DVD or VHS format.
We always have at least one DVD or VHS tape for each movie we track, and each DVD or VHS
tape is always a copy of a single, specific movie.
Our DVDs and VHS tapes are very long. We don’t have any movies that require multiple DVDs
or VHS tapes."
"We are frequently asked for movies starring specific actors. John Wayne and Julia Roberts are
always popular. So we’d like to keep track of the star actors appearing in each movie. Not all of
our movies have star actors. Customers like to know each actor’s “real” birth name and date of
birth. We track only actors who appear in the movies in our inventory.
We have lots of customers. We rent videos only to people who have joined our 'video club.' To
belong to our club, they must have good credit. For each club member, we’d like to keep their
first and last name, current phone number, and current address. And, of course, each club
member has a membership number.
Then we need to keep track of what video tapes each customer currently has checked out. A
customer may check out multiple video tapes at any given time. We just track current rentals. We
don’t keep track of any rental histories.”
We would like to keep the rental date/time and the return date/time. All our tapes are due back
the next day, so we don’t need to keep a due date. Keeping this rental history will allow us to
analyze the pattern of our rentals. We will be able to determine how many tapes each customer
rents and how many times a customer has returned a tape late. We will also know how many
times a particular tape has been used and will then know when to retire each tape. We will also
be able to analyze our customers’ movie preferences.”
